Abstract: A coin wrapping mechanism for wrapping rolls of coins is disclosed. The mechanism comprises coin stacking means for forming a coin stack (30) containing a predetermined number of coins, a substrate (26) for supporting a selected length of a wrapping material (10) having a coating (21) of a pressure-sensitive, releasable adhesive on the side facing away from the substrate, and wrapping means (36,37) for bringing the coin stack (30) and the supported length of wrapping material (10) into engagement with each other. Once engagment occurs relative movement is effected between the coin stack (30) and the substrate (26) while allowing the coin stack (30) to rotate, so that the wrapping material (10) is adhered to and wound around the coin stack (30) by the rotation of the coin stack. As the coin stack is wrapped the wrapping material is cut and a new amount of wrapping material is fed to the substrate for wrapping the next stack of coins.

Abstract: The invention relates to a method for the manufacturing of a wind barrier or breather web (7), especially in connecti­on with the manufacturing and mounting of construction ele­ments, as well as a method for the manufacturing of a spe­cial web in which such a wind barrier is included. The in­vention is to the fact that a filt web (7a) is joined with a plastics layer (7b) which in connection with its applica­tion to the filt (7a) provides zones allowing for the dif­fusion of moisture through an otherwise waterand windproof finished web product (7). Possibly, there may be used a crude plastics material which is mechanically foamed or comprises an additive which under the influence of heat creates vapour blisters or gas pockets which provide thin fields and together with the embossing function of the filt and/or the press rollers onto the plastics layer form the diffusion zones. The novel wind barrier or breather web has a small mass and thus provides a final product which is very little fire incentive. The wind barrier web is also applicable for further treatment in the form of a special web, a so-called integrated ground beam membrane which re­places the use of separate mineral wool strip,impregnated foundation wall felt and breather paper in connection with a beam arrangement on concrete foundation.

Abstract: Covers for semiconductor packages are made by diffusion pressure bonding a coated substrate to a preform at a temperature below the melting point of the preform alloy. An alloy preform is coated on one side with a thin layer of the preform alloy component that has a lower melting point than the preform alloy, preferably the lowest melting point. Coated substrate and coated preform are assembled and the assembly is compressed and heated below the melting point of the preform alloy but above the melting point of the preform coating to form a diffusion pressure bond between substrate and preform.

Abstract: In a regulation method for the air to fuel ratio of a combustion engine, the output voltage of an oxygen-measuring probe, which is located in the exhaust pipe of the combustion engine, being fed to a regulator and the regulator emitting a control variable for the air to fuel ratio, signals corresponding to the load and speed of the combustion engine are also fed to the regulator which includes a microprocessor. Following any sudden change in the output voltage of the oxygen-measuring probe there is a sudden change in the control variable. The control variable is formed by adding a default value and an additional value. The additional value is in each case derived by multiplying a coefficient dependent on the load and speed by a numerical variable, and the numerical variable is set to 0 by each sudden change in the output voltage of the oxygen-measuring probe. <IMAGE>
